STENOGRAPHIC MACHINE.

SPECIFICATION forming part of Letters Patent No. 352,799, dated November16,1886.

Application filed March 1' 1885.

To all whom it may concern:

Be it'known that I, MILEs M. BARTHOLO- MEW, of Belleville, in the countyof St. Clair and State of Illinois, have invented a certain new anduseful Improvement in Stenographic Machines, ofwhich the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

Figure 1 is a top view of the machine. Fig. 2 is a transverse verticalsection at 2 2, Fig. 1. Fig. 3 is a rear elevation of the machine withpart of the case broken away. Figs. 4 and 5 are detail transversesections, showing the different positions of the stop-lever.

A is the base of the machine.

B is a case or frame in which the drive mechanism has bearing. Thismechanism has a barrel, 0, containing a coiled spring, by which thebarrel isturned, the spring having one end attached to the barrel andthe other end attached to the winding-shaft D, in the usual manner. Theshaft D has fixed upon it a ratchet-wheel,E, which is prevented frombackward rotation by a pawl, F, pivoted to the case B, andheld incontact with the ratchet-wheel. The winding-shaft D has an angular end,D, for the engagement of the winding-key. The style of key which isshown is a ratchet'key having a handle, H, in which is j ournaled aratchet wheel, G, having a central angular socket fitting the end D.This wheel is en gaged by a pawl, I, pivoted to the handle, thearrangement being such that the oscillation of the key will Wind up thespring in thebarrel 0. Upon the barrel 0 is a cog-wheel, J ,which isconnected with the fly-shaft L by a train of gearing, K, causing thefly-shaft to revolve at a high velocity as compared with the barrel 0.

M is the fly upon the fly-shaft L. One of the shafts, as N, of the trainof gearing carries the paper-feed roller 02 The paper roll is shown atP, the paper ribbon extending beneath the feed-roll O and over asupporting-roll, R, which serves to press the paper ribbon againsttheunder side of the feed roll. The supporting-roll has bearing on aspringarm, S, secured to the standard T, upon which the paper roll iscarried, the spring-arm being hinged to the staudard and having aprojection, S, whose free end is connected to the base A by a spiralspring, U, and a thumb- Serial No. 159,151.

nut, U, turning on the spring-rod and bearing upon the top of theprojection.

Vare the keys, carrying markers V, which on the depression of the outerends of the keys are carried up against the ink-ribbon W, and serve tomake a mark on the paper ribbon, the paper and ink ribbons passingtogether between the markers and an abutment-piece, X.

The ink-ribbon is coiled on two reels, Y and Y, which carryfriction-disks Zand Z, and are supported on'asliding frame, a, thatsupports a friction-wheel, Z which is in frictional contact at itsperiphery with the periphery of the disk Z. By the endwise movement ofthe frame a either the disk Z or disk or wheel Z may be brought intofrictional contact with the shaft N, or with a smallfriction-wheelthereon, so that either the disk Z or that Z may be turnedto wind up the ink-ribbon, the other one of thesedisks being free toturn, and thus allow the ribbon to be unwound from its roller. The framea may be moved by means of aliendie, I). c is a spring-pawl, whichengages a tooth, (1, upon the top of the frame a, and prevents theaccidental movement of the frame.

The reels YY have knobs by which they may be turned by hand.

It will be seen that the paper ribbon is pushed forward between theabutment piece or plate X and the marker by the feed-roll O to therearof the marker; The construction is such that the feed of the paperbetween the rolls 0 and B may be continuous, and yet the paper mayremain at rest at the point pressed by the marker, the paper curvingbetween the rollers and the marker. Then as soon as the paper isrelieved from the pressure of the marker it returns to astraightcondition. By the described construction the friction of the paperagainst the ink-ribbon, when they are pressed together, is avoided andthe consequent blurring of the mark.

The fly M should not be rigidlyattached to its shaft, but should havefrictional contact therewith, so that the arrested rotation of the flyshall not cause the sudden arrest of the fiyshaft. This arrangement iscommon in striking clocks.

I will now describe the device for stopping the motion of the drivingmechanism.

' e is a shaft having at one end. a key, f, and i at the other end afinger, f, which by thedepression of the key is brought into the course2. The combination, with the fly M, for the purpose set forth, of thestop device eff g, substantially as and for the purpose set forth.

3. The combination of an abutment-piece, a marker for forcing theink-ribbon against the paper strip and the abutment, and a feed device,substantially as described, to the rear of 20 the marker, flexing thestrip when detained by the pressure of the marker.
